GRATE'AND LINING.

SPECIFICATION forming part of Letters Patent No. 231,658, dated .Iuiy24, 1882.H

jApplication filed October 2S, 1882. (No model.)

'of Illinois, have invented an lImprovement in Grates and Linings, ofwhich thefollowing is a specification, to wit:

My invention relates to combined stove grates and linings; and itconsists in a series of bars so formed that they may be combined to forma grate oi' any required size, the bars of which are separated by smallcastings; or by omitting` the small castings they may be throwntogetherto form a lining for the backs and ends of stoves and applied either asa grate or lining to any stove, substantially as will bc hereinaftermore fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the accompanying drawings, inwhich- Figure l is aperspeotive view of a part of a grate, such asIdescribe. Fig. 2 is a similar view of the device arranged for astove-lining. Fig. 3 is a view of the two end pieces and the centralbars upon which the gratebars are arranged. Fig. 4 is a View oi' oneofthe grate-bars. Fig. 5 shows one of the small'castings which separatethe grate-bars.

. Fig. 6 is a view of one of the grate-bars havare laid upon them.

ing the small castings formed on the ends, and showing the shakingdevice applied there-4 to; and Fig. 7 is a view of one of the devicesfor elevating or lowering the grate.

A represents the grate-frame, which I cast in pieces, each containingone side and one end, having on their inner edges a series of smallcross-bars, a a, projecting above and below the frame, as seen in Fig.l, and' these pieces, when put together, are secured by thelinterlocking of the small cross-bars a a to form a frame, whose lengthand width may be varied to suit any sized stove. The sides and ends ofthis frame are also provided with holes a', by which air is allowed to`circulate, and may also -be used for the passag of bolts...

B designates an end of my graty cast with the: central bars, B B, whichare beveled from their? upper inner edges downward and outward, asshown, and formed with serrations b across their upper edges, which formpassages for allowing the free circulation of air when the grate-barsNear each end the end piece B is formed with two openings, b, and

two downward projections, b, on its under side, one of which is at theextreme end of the bar, and one depending between the openings b', asseen clearly in Fig. 3. In the center the piece B is provided with acentral opening, b3, and from the side opposite the bars B projects ahorn, B2, which forms the pivot upon which the grate turns upon theframe A or in the end of the stove. f

C designates a grate-bar, formed with a central projection, C', which isT-shaped on its lower end. The bar C is formed wider at one end than theother, and provided at each end with a lug, c, projecting -froin itslower side, as shown inFigs. l and 4. The bars C are slipped on thecentral bars, B, the shanks c of their central projection or lug, C',passing between the bars B B and the T-headc2 resting in longitudinalannular grooves b4 in the lower inner edges of the bars B. The gratebarsC are placed with their wide and narrow ends alternating, as representedin Fig. 1. To keep'the grate in proper shape, and to separate them fromveach other, I place between them, upon the bars B', a small casting, D,having a T-lug, D, on its lower side, corresponding in form and purposeto the similar length, the ends of the bars B are inserted inlcorresponding-shaped openings e in an end piece, E, which is otherwiseformed exactly similar to the piece B, with end openings, e,

projecting lugs e2, central opening, e3,- and apivotal horn, E.

If it is desired to provide means for shaking the grate, I'pass throughthe openings b ein the end pieces, B E, a small loop of metal, d, openon one side, as shown, for the passage ofthe lugs b2 e2, and in theseloops is suspended, as seen in Fig. 1, abar, F, formed with smallcross-bars j', which pass between the projecting lugs c on thegrate-bars,and when this bar is given a reciprocating motion by means ofa common stove-lifter or iron rod the bars j" f strike the lugs c andcause the grate bars to oscillate, thereby effectively cleaning them ofashes andcinders.

I iind it most convenient to cast the small separating-pieces D on theends of the gratebars C, as shown in Fig. 6, and when wanted for usethese separating-pieces D may be knocked ott` the grate-bar. In somecases, however, the grate-bar may be found too short for the size of thestove to which itis desired to fit a grate, and in that ease one or bothof the small pieces D may be left in position as cast, and form a longergrate-bar. "il/'hen this is done, it will be found better to lay theshaking-bar F in position upon the pieces D, as seen in Fig. 6, and thebars may then be shaken, as before described. As illustrated in Fig. 2,these grate-bars maybe formed into a stove-lining by slipping` them onthe bars B' B' close together, with the wide and narrow endsalternating, as when forming a grate. Thus the sides and ends of thestove-furnace are formed, and are secured together bypassing the horn orarm B2 of one of the end pieces through the central opening, c, of theother end piece. \Vhen it is necessary to form a lining for stoveshaving a flaring fire-place, the bars C are for a certain distance fromeach end slipped on thebars B' B', with theirlarge and small endscorresponding with each other, instead of alternating, and thus thelining is formed with beveled ends, which, when placed together, fit theflare of the lire-place in the stove.

Fig. 7 shows a small casting, consisting of a ring, G, provided on oneside with a U -shaped clasp, G', which is slipped on the grate-frame toform a bearing for the grate when there is none on the stove, or itmaybe turned either up or down, to raise or lower a grate to any desiredposition. The ring G may also be used without the clasp G', to form awasher on one ofthe horns or pivots of the end pieces of the grate toprevent too much endwise movement.

Such a device as I have described forms an exceedingly cheap andconvenient grate which may be packed away into very small colnpass andput together at any time, and of any size to lit whatever stove isdesired, and the same pieces are susceptible of being used to forln astove-lining, which will be found very convenient by dealers ineffecting repairs in stoves that`have had their grates and liningsburned out.

The openings b' e' in the end pieces of the grate are very convenientfor securing a leg upon which to rest the grate in stoves intended forburning wood, but which it is desired to convert into coal-burners, andthe grates and lining being easily taken apart and put together, it isconvenient for repairs when one or two of the bars may be burned out,being easily replaced without the expense of a new grate or lining.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a stove-grate the end piece B, provided with the central bars, B',in combination with the end piece E, formed with sockets e, to receivethe bars B', substantially as and for the purpose set forth.

2. In astove-grate, the end piece B, formed with horn B2, bars B',openings b', projections b2, and central openings, b, in combinationwith the piece E, cast with sockets e, openings e', projections c,central opening, (5*, and horn E', substantially as shown and described.

3. In a stove-grate, the central bars, B' B', having beveled outerfaces, serrations I) across their upper face, and the grooves b on theirinner lower edges, substantially as and for the purpose set forth.

4. In a stove-grate, the bars C, cast with a downward projection, c, ateach end, and a central. T lug or projection, C', in combination withthe central bars, B', substantially as and for the purpose set forth.

5. In a stove grate or lining, the bars (l, formed wider at one end thanat the other, in combination with the central bars, B', upon which theyare removably secured, substantially as and for the purpose set forth.

6. In astove-grate, independent bars loosely secured to two central barscast with the end pieces, in combination with the smallseparating-castings D, provided with a T-shaped lug on their under side,substantially as shown and described.

7. In a grate for stoves, the end pieces, B E, cast with the endopenings, b' c', and the central supporting-bars, B', upon which areslipped the independent bars C and separating-pieces D, in combinationwith the suspending-loops di' and shaking-bar F, formed with cross-lugsff, substantially as shown and described.

8. In combination with a stove-grate composed of a series of independentbars loosely secured to central supporting-bars the shaking-bar F, eastwith the cross bars or lugsff, and suspended to the end bars ol' thegrate, whereby a reciprocating motion of the shaking-bar will impart anoscillating movement to the grate-bars to remove ashes and cinders,substantially as shown and described.

9. rlhe combination of the end pieces, B E, and the centralsupporting-bars, 3', with the tapered grate-bars C, cast with a T-shapedlug under their center, whereby they may be formed into either astove-grate or a stovelining of varying size and shape, substantially asshown and described.

10. A grate-frame cast in pieces, each containing one side and one end,and provided with locking-lugs along their inner edges, whereby they maybe combined to form a frame of any desired length and width, and adaptedto be locked together by said lugs, substantially as shown anddescribed.

In testimony whereof I affix my signature in presence of two witnesses.
